This one is tricky.
Table export is intentionally decoupled from general export settings:

org-table: Fix radio tables containing macros

* lisp/org-table.el (orgtbl-to-generic): Export macros as-is, even if
  they are undefined.
* testing/lisp/test-org-table.el (test-org-table/to-generic): Add test.

Radio tables are now using a minimal set-up for export.  In particular,
no macro is expanded, and no Babel code is executed.  If any of these is
needed, use `org-export-string-as' or `org-export-region-as' instead.

I understand that the suggested `org-export-region-as' will not work
because we don't have ox-csv. And changing the way table export works
may cause unforeseen consequences.

I have to think how to approach this problem.
